Perimeter and circumference - HiSET

The perimeter of a regular octagon - the sum of the lengths of its (eight congruent) sides - is eight times the common sidelength, so the perimeter of the octagon is feet. One yard is equivalent to three feet, so divide this by conversion factor 3 to get yards - the correct response.

The length of one side of a square is equal to the square root of its area, so, if the area of a square is , the common sidelength is . Since a square comprises four sides of equal length, the perimeter is equal to four times this length, or .

A regular octagon has eight sides of equal length. Its perimeter is equal to the sum of the lengths of its sides, so the length of one side can be computed by dividing the perimeter by 8, as follows:

,

the correct response.

A regular hexagon can be divided into six equilateral triangles, as follows:

The perimeter of Trapezoid can be seen to be .

Perimeters can be calculated using the following formula.

In this formula, the variable, , represents a side of the polygon.

Substitute and solve.
